ELBOW 0R FITTING.

Specification. of Letters Patent.

Original application filed June 6, 1912, Serial No. 701,970, Divided and this application filed January 22, 1914, Serial No. 813,658. Renewed July 11, 1918. Serial No. 244,489.

To all whom it may concern Be it known that I, JULIAN G. Groom-Inn, a citizen of the United States, residing at Chicago, in the county of Cook and'State of Illinois, have invented 'a certain new and useful Improvement in Elbows 0r Fittings, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to an improved form of elbow or fitting, and has as its principal object the provision of a device which will reduce the labor and expense in installing systems of piping, as in disinfecting systems.

A further object resides in the particular arrangement and combination of parts here inafter described.

In the accompanying drawings which form a part of this specification Figure l is an elevational View of my improved device as mounted on the top of two intersecting walls;

Fig. 2 is an elevational view of a modified form of my device similarly mounted;

Figs. 3 and 4 are end elevations of the devices shown in Figs. 1 and 2, respectively;

Fig. 5 is a plan view of the device shown in Fi 1.

Refining more particularly to the drawing 38 and 39 are fragments of two vertical walls intersecting at right angles. 36 is an elbow comprising two arms of approximately equal length intersecting at right angles. Each arm is hollow and substantially circular in cross section, except that it is slotted as shown at- 60 or 61, so that the two arms have an are shaped cross section. -These slots 60 and 61 are formed with edges which lie in planes at right angles to each other, so that one edge may contact with the top edge of the wall and the other edge may drop below the top edge of the wall and contact with the vertical face of the wall. The first mentioned edge is parallel to the plane determined by the central axes of the two arms of the elbow. As shown in Fig. l the two vertical edges of the slots lie on the inside of the angle between the walls 38 and 39.

Referring more particularly to Fig. 2, 37 is an elbow which is similar in most respects to the device 36. Device 37 however, is

shown as mounted on top of the walls 62 and which are vertical walls intersecting at right angles. The device 37 is'mounted on top of'these walls at their point of intersection, and like the device 36 is provided with slots 60 and 61 The device 37, however, differs from 36 in that the vertical edges of the slots 60 and 61 are upon the outside of the corner formed by the walls 62 and 63.

The subject matter of this application is divided from my co-pending application, Serial No. 701,970.

Having thus described my invention, what I claim is:

l. A device of the class specified comprising a curved tubular member having a side portion provided with a right angled slot, the opposite edges of said slot forming con tinuous shoulders disposed at right angles to each other.

2. An elbow provided with two intersecting arms substantially at right angles to each other, said arms having intersecting slots, two intersecting edges of said slots lying in planes at right angles to each other and also at right angles to a plane determined by the central axes of the two arms.

3. An elbow provided with two intersecting arms substantially at right angles to each other, said arms having intersecting slots, two intersecting edges of said slots lying in planes at right angles to each other and also at right angles to a plane determined by the central axes of the two arms, the other edges of said slots lying in a plane which is parallel to the plane of said axes.

4. A device of the ,class specified comprising a curved tubular member having a side portion which is formed to produce continuous shoulders which are disposed at right angles to each other.

5. An elbow provided with two intersecting arms substantially at right angles to each other, said arms having intersecting cutaway portions, the intersecting edges of said cut-away portions being continuous and lying in planes at right angles to each other and parallel with a plane determined by the central axis of the two arms.

6. A device of the class specified comprising a curved tubular member having its under side provided with a flat surface and Patented Feb. at, 19119..

also with angularly disposed vertical surfaces arranged to cooperate with said flat surface, the fiat and vertical surfaces of each arm being continuous from one arm 5 to the other.

7. A device of the class specified comprising a curved tubular member having its under side provided with a substantially V- shaped slot having a horizontal flat surface,

and also with angularly disposed vertical surfaces arranged to cooperate with said horizontal flat surface.

8. A device of the class specified comprising a curved tubular member having a side portion which is formed to produce a right angled cut-away portion, said cutaway portion producing meeting shoulders similar portion of the other member a continuous V-shaped shoulder which is disposed transversely to the shoulder of the opposite portion.

In Witness whereof, I hereunto subscribe my name this 21st day of December, A. 1).,
